A group of Court Street business owners in Carroll Gardens and Cobble Hill are suing the City of New York and the Department of Transportation, claiming a new protected bike lane is choking traffic and hurting local businesses.

The Court Street Merchants Association filed the petition last Friday, challenging the redesign that removed a traffic lane and curbside parking to make room for a protected bike lane.

Joan D’Amico, who owns D’Amico Coffee, says sales have dropped since the lane went in earlier this month.

“If I have a customer who wants to run in for a cup of coffee, there’s nowhere for them to park,” she said.

James Caputo, owner of Caputo Bake Shop, says his bakery — open for five generations — is down 30% since the project began earlier this month.

“I’m afraid this could be the death of Court Street,” Caputo said. “I hear a lot of complaints from all of my customers. They call me, they email, they can't find any place to park. So, they drive by, they look for parking, and they just keep going and the problem is, once they find an alternative, they're not coming back.”

The DOT says the redesign, which also added pedestrian islands and loading zones, was done to improve safety for everyone.

"This particular design was not consulted with anyone in the community, business owners, residents, no one,” said neighbor Mark Scotto.

The lawsuit asks a judge to toss the redesign and require the city to work with the community on an alternative.

"Just let us have some input,” D’Amico pleaded. “There's possible changes that they can make where it's more conducive to everyone."

But not everyone's against it.

"I think it's a wonderful thing and we should do it everywhere,” said Dan, who was riding his bike.

A spokesperson for DOT told News 12, "The redesign of Court Street follows the best safety practices from around the world and is similar to countless streets across New York City. Protected bike lanes have proven to enhance safety for everyone on the road, while also helping support local businesses, and we look forward to defending the project in court."
